I need to replace the dead SLA battery in my 36V, 500watt EV Global bike and want to keep the battery within the existing down tube compartment. I found a water bottle case, 10 AH, 15A max discharge, 92mm X 360mm, 18650 cell battery pack from Bat-Bike on Ebay that should fit into the down tube compartment. My concerns are: Will the battery in the aluminum case overheat in the down tube compartment? Compartment has vents in the front and back. Is the battery 15A max discharge rate sufficient for the 500 watt motor (500w/36v=13.88A Right?) for casual, less than 10 mile rides? Has anyone done business with Bat-Bike out of Jacksonville FL? There E-bay ad does not contain much info as to the BMS or the provided charger. It looks like bikes are there main business and batteries are a sideline.
Does anyone have a better idea? I desire to keep the battery in the existing down tube battery compartment and get as much capacity per $$$ as I can. Most of the battery packs I’ve found on the web are too large to fit in the existing 4”x4”x14.5” compartment. I have the existing battery case, but it is a little warped, and I do not have the skills fix it and install 18650 cells.
